Genes affected

ADGRV1 (HGNC:17416): (adhesion G protein-coupled receptor V1) This gene encodes a member of the G-protein coupled receptor superfamily. The encoded protein contains a 7-transmembrane receptor domain, binds calcium and is expressed in the central nervous system. Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures. Several alternatively spliced transcripts have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.30061507).

The p.Leu4358Phe variant in GPR98 has not been previously reported in individual s with hearing loss and was absent from large population studies. Computational prediction tools and conservation analyses suggest that the p.Leu4358Phe variant may impact the protein, though this information is not predictive enough to det ermine pathogenicity. In summary, the clinical significance of the p.Leu4358Phe variant is uncertain. -
